At that point, the entire coaching staff and parents of the young players ran onto the field to confront Keigans. As Keigans started walking off the field, the Saints' assistant coach ran towards him and slapped him on the face with his left hand.

The slap sent Keigans to the ground and knocked his hat off. The entire incident was captured on a video posted to YouTube.

The assistant coach was later identified as 43-year-old Dion Robinson. He hasn't been arrested yet but could face an assault charge, the BSO said.
